Reconstitution of membrane proteins in phospholipid vesicles allows the investigation of such macromolecules in a biomimetic simplified environment. The often employed micelle-to-vesicle-transition method for proteoliposome preparation is a fast and reproducible technique. In this, communication is shown that the lipid/protein ratio influences the size of the proteoliposomes and the actual protein reconstitution. The results indicate that for photosynthetic reaction centres, the best conditions for ligand-interaction experiments are achieved with a lipid/protein value of 1000:1, while for complete protein incorporation, the 2000:1 ratio should be chosen.
